A system and related techniques integrate the accessing, retrieving and
playback of enhanced music or other digital media or content, including
to permit advanced authoring, mixing and environmental inputs and
effects. According to embodiments of the invention in one regard, a user
may access a playback engine to retrieve and dynamically mix, manage and
integrate music content with environmental sensors and effects such as
detection people or numbers or people, lighting effects and other sensory
experience. Thus the tempo of a mixed music track may vary with the
number or persons in a room or the time of day or night, or lighting
effects may brighten or dim based on dynamic contrasts in the music or
other content. According to further embodiments, the playback engine may
permit a user to link or navigate to other community resources such as a
Web site detailing an artist, album, movie or soundtrack, or a bulletin
board for consumers with an interest in artists, actors or others.
Because the music authorizing format and reproduction system may
compatibly operate on musical and other content containing defined media
extensions and permit the content to be freely mixed and integrated with
environmental inputs and effects, the richness and participation of the
musical and other playback experience for the user may be enhanced.
